Maths 1 More Than and 1 Less Than Number Activity: Within 5, 10, 15 & 20

**FUN, hands-on activity for teaching 1 more and 1 less than numbers to 5, 10, 15 and 20. Included are 10 differentiated charts, number lines and ‘show me’ windows! Teach children to search for 1 more than a number, 1 less than a number or both with this alien-themed activity! **

This activity can be used for a whole-class introduction, as a guided group activity or in your maths area. Just print and laminate the charts. To make the Show Me windows, laminate and cut around the frame, cut out the square/rectangular box in the middle and then place over a chart to search for numbers! Alternatively, you could use the black and white versions of the charts as ‘number search’ printables.
